Treatment Strategy

Damage from the boxwood psyllid is mostly aesthetic. Depending on the situation, control may not be necessary. If the population is identified early enough, pruning out affected areas is a possibility. Another option is to use systemic insecticides like Xytect™ or Transtect™, which work from the inside of the plant, controlling actively feeding psyllids.

Treatment Expectations

This is not a pest that will kill or seriously disfigure plants. At most, it causes some curious looking foliage in the spring which grows out by summer. If control is necessary, timing must be made top priority. Though the adults feed later in the year, the nymphs do most of the damage and should be targeted. Boxwood leafminer will also be controlled by a Xytect™ or Transtect™ treatment.
